Vrenor (Frenor in the NES version) is a location in Dragon Quest IV. Located in the northeast of Zamoksva, it is a highly gossipy small town.
Alena, Borya and Kiryl travel to Vrenor in Chapter 2 and encounter the Fake Princess of Santohaim and her retinue. After her capture, the kidnappers place the Armlet of Transmutation as her ransom; the party, having acquired the item earlier in their travels, gives it up to ensure the girl's safety. After this, they move on.
